8 Hazards identified in Annex A of EN 1050:1996 Table 1 Hazards and associated requirements Relevant clause of Annex A of EN ISO :2003 Relevant clause of this standard Insufficient instructions for the user of the steel wire ropes and the machinery manufacturer Safety instructions and information for use and maintenance 5.1 General Information shall be provided on the subjects listed in 5.2 to Use and maintenance This information shall include temperature limits, use in exceptionally hazardous conditions, first use, handling and installation and maintenance. An example of such information is given in Annex A. 5.3 Rope selection For stranded ropes this information shall include guidance on rope construction in relation to abrasion and wear, type of core in relation to crushing of the rope at the drum, wire finish in relation to corrosion, direction of lay and type in relation to direction of coiling, rotational characteristics in relation to use of a swivel and fleet angle effects. An example of such information is given in Annex B. 5.4 Material health and safety information on steel wire rope and its component parts This information shall include details of all the individual materials that form part of the finished rope and general information relating to occupational protective measures, emergency medical procedures, safety (including any fire or explosion hazards) and disposal. An example of such information is given in Annex C. 6

9 Annex A (informative) Example of general information for use and maintenance A.1 Limitations on use due to adverse environmental conditions A.1.1 Temperature A Steel wire ropes made from carbon steel wires Account should be taken of the maximum temperature that may be reached by the wire rope in service. An underestimation of the temperature involved can lead to a dangerous situation. Stranded ropes with fibre cores or fibre centres can be used up to a maximum of 100 C. Stranded ropes with steel cores and spiral ropes (i.e. spiral strand and locked coil) can be used up to 200 C although some de-rating of the working load limit is necessary, the amount being dependent upon the exposure time at high temperature and the diameter of the wires. For operating temperatures between 100 C and 200 C the loss in strength may be assumed to be 10 %. For temperatures above 200 C special lubricants may be necessary and greater losses in strength than stated above will need to be taken into account. The rope or machinery manufacturer should be contacted. The strength of steel wire ropes will not be adversely affected by operating temperatures as low as 40 C and no reduction from the working load limit is necessary; however, rope performance may be reduced, depending upon the effectiveness of the rope lubricant at low temperatures. When the rope is fitted with a termination, also refer to A A Terminations In addition to the limits stated above for rope, and unless otherwise specified by the rope manufacturer or the manufacturer of the machine, equipment or installation, the following operating temperatures must not be exceeded: Turn-back eye with aluminium ferrule: 150 C Ferrule-secured eye with steel ferrule: 200 C Socket filled with a lead-based alloy: 80 C Socket filled with zinc or a zinc-based alloy: 120 C Socket filled with resin refer to resin socketing system designer s instructions A.1.2 Use in exceptionally hazardous conditions In cases where exceptionally hazardous conditions are known to exist, e.g. offshore activities, the lifting of persons and potentially dangerous loads such as molten metals, corrosive materials or radio active materials a risk assessment should be carried out and the working load limit selected or adjusted accordingly. 7

10 A.2 Before putting the rope into first use A.2.1 Inspecting the rope and documents The rope should be unwrapped and examined immediately after delivery in order to check its identity and condition and to ensure that the rope and its termination(s), if any, are compatible with the machinery or equipment to which they are to be attached in service. NOTE 1 If damage to the rope or its package is observed, this should be recorded on the delivery note. The Certificate of conformity by the rope manufacturer should be kept in a safe place, e.g. with the crane handbook, for identification of the rope when carrying out periodic thorough examinations in service. NOTE 2 The rope should not be used for lifting purposes without the user having a Certificate in his possession. A.2.2 Storing the rope A clean, well-ventilated, dry, dust free, undercover location should be selected. The rope should be covered with waterproof material if it cannot be stored inside. The rope should be stored and protected in such a manner that it will not be exposed to any accidental damage during the storage period or when placing the rope in, or taking it out of, storage. The rope should be stored where it is not likely to be affected by chemical fumes, steam or any other corrosive agents. If supplied on a reel, the reel should be rotated periodically during long periods of storage, particularly in warm environments, to prevent migration of the lubricant from the rope. The rope should not be stored in areas subject to elevated temperatures as this may affect its future performance. In extreme cases its original as-manufactured breaking force could be severely reduced rendering it unfit for safe use. The rope should not be allowed to make any direct contact with the floor and the reel should be so positioned that there is a flow of air under the reel. NOTE Failure to ensure the above may result in the rope becoming contaminated with foreign matter and start the onset of corrosion even before the rope is put into service. Preferably, the reel should be supported in an A-frame or cradle standing on ground which is capable of safely supporting the total mass of rope and reel. The rope should be inspected periodically and, when necessary, a suitable rope dressing, which is compatible with the manufacturing lubricant, should be applied. Any wet packaging, e.g. sackcloth, should be removed. The rope marking should be checked to verify that it is legible and relates to the certificate. When removing from store, the principle 'first in, first out' should be applied. 8

11 A.2.3 Checking the condition of rope related parts of the machine, equipment or installation Before installing the new rope, the condition and dimensions of rope related parts, e.g. drums, sheaves and rope guards, should be checked to verify that they are within the operating limits as specified by the original equipment manufacturer. For ropes working on cranes the effective groove diameter should be at least 5 % above the nominal rope diameter. The groove diameter should be checked using a sheave gauge. Sheaves should also be checked to ensure that they are free to rotate. Under no circumstances should the actual rope diameter be greater than the pitch of the drum. In the case of multilayer coiling, the relationship between the actual rope diameter and the pitch should be assessed. When grooves become excessively worn, it may be possible to have them re-machined. Before doing so, the sheave or drum should be examined to determine if sufficient strength will remain in the underlying material supporting the rope after the machining has been carried out. NOTE When grooves become worn and the rope is pinched at it sides, strand and wire movement is restricted and the ability of the rope to bend is reduced, thus affecting rope performance. A.3 Handling and installing the rope A.3.1 General The procedure for installing the rope should be carried out in accordance with a detailed plan issued by the user of the steel wire rope. The rope should be checked to verify that it is not damaged when unloaded and when transported to storage compound or site. During these operations, the rope itself should not come into contact with any part of the lifting device, such as the hook of a crane or a fork of a fork lift truck. Webbing slings may be helpful. A.3.2 Rope supplied in a coil The coil of rope should be placed on the ground and rolled out straight, ensuring that it does not become contaminated with dust, grit, moisture or other harmful material. The rope should never be pulled away from a stationary coil as this will induce turn into the rope and form kinks. If the coil is too large to physically handle it may need to be placed on a turntable which will allow the rope to be paid out as the end of the rope is pulled away from the coil. Correct methods of paying out rope from a coil are shown in Figure A.1. 9
